Compass adjusts the way partials are imported. It allows importing components based solely on their name, without specifying the path.

Before you can do @import 'compass';, you should:

Install Compass as a Ruby gem:

gem install compass

After that, you should use Compass's own command line tool to compile your SASS code:

cd path/to/your/project/
compass compile

Note that Compass reqiures a configuration file called config.rb. You should create it for Compass to work.

The minimal config.rb can be as simple as this:

css_dir =   "css"
sass_dir =  "sass"

And your SASS code should reside in sass/.

Instead of creating a configuration file manually, you can create an empty Compass project with compass create <project-name> and then copy your SASS code inside it.

Note that if you want to use Compass extensions, you will have to:

1. require them from the config.rb;
2. import them from your SASS file.
